IMPROVEMENT IN BRACKETS.

Specification forming part of Letters Patent No. 118,433, dated August29, 1871.

To all whom it may concern:

Be it known that I, JAMEs E. CrmsLEY, of Boston, in the county ofSuffolk and State of Massachusetts, have invented certain Improvementsin Brackets, of which the following is a specification My inventionrelates to the combination of dovetailed grooves and tenons with abracket, in such a manner that the shelf may be temporarily connected tothe back piece and the support to the shelf in a very strong manner, ormay be instantly removed, when desired, to pack the same in a smallcompass for removal or shipment.

Figure l is a vertical transverse section through the back, shelf, andsupport. Fig. 2 is a vertical section through the shelf and support at aright angle to the view in Fig.1, at the point indicated by dotted linesa m.

A A represent the back piece having a dovetailed groove across its frontside. B B represents the shelf, having upon its back edge adovetail-tenon corresponding to the groove across the back piece. 0 isthe support for the shelf. The shelf is provided with a dovetail-grooveupon its under side, commencing at its rear edge and extending forward,terminating at about the point shown in Fig. l, at E. The upper end ofthe support 0 is provided with a dovetail-tenon corresponding with thegroove in the shelf, but of less width than the length of the groove towhich it is to be applied, the dovetail-tenon being cut away at thefront of the support a sufficient distance to allow it to be slidforward into the groove in the shelf so as to admit the pin to pass infront of the back piece. When the shelf is slid to its place the supportis slid back, and the. pin is pressed into the hole made in the backpiece to receive it.

To disconnect the bracket, pullthe support G forward to disengage thepin, then draw the shelf B sidewise from the dovetail-groove in the backpiece, then pull the support in a like manner from the shelf, and thethree pieces may be laid flatwise upon each other so as to pack in asmall compass, and may be carried without danger of breakage, and,whenever desired, may be readily and easily put together in a firmmanner ready for use without nails or the aid of tools.

I claim as my invention--- As a new article of manufacture, a bracketwith dovetailed grooves and tenons, combined with back piece A, shelf B,and support C, when con-.
